Trying to find out that how many loop cycle it complete before the 'S' become zero. S value is not decreasing. Need to decrease S value zero and sum the total cycle number?

>> C=0.02;

>> cycle = 0;

>> FC =0;

>> S=10;

>> while (S>=0)

S=(S-F);

F=(S*C);

FC = (FC+F);

cycle =(cycle+1);

end

Doesn't the "cycle" variable give you this count?

Hello James thanks for the comment. The value of S is not decreasing. It need to decrease every cycle. S is not decreasing and cycle number is very high.

hello

F is undefined in your code ...

Correction :

F is not initialized in your code ...

hello again

so I made 2 modifications

• initialized F with 0 (my guess)
• changed the while tolerance limit because otherwise it never ends , S continues to get smaller and smaller but never goes to zero;

C=0.02;
cycle = 0;
FC =0;
F = 0;
S=10;
tol = 1e-10;
while (S>=tol)
    S=(S-F);
    F=(S*C);
    FC = (FC+F);
    cycle =(cycle+1);
end

F is negative. You need to decide whether F should be positive and be subtracted, or if it should be negative and be added.

I would suggest to you that it would be more consistent logically for F to be negative and be added.
